Answer:
The HSC-20T is built with an extruded aluminium body, die-cast aluminium top and bottom covers, and an aluminium mesh grille lined with an internal foam dust barrier. It provides weather and dust resistance, a directional sound beaming pattern, and an external bottom-mounted rotary switch for tap selection.
The Hitune HSC-20T features a specialized mechanical and acoustic enclosure engineered for speech intelligibility in challenging acoustic environments:
- All-Aluminium Enclosure: Constructed with an extruded aluminium housing profile coupled with die-cast aluminium top and bottom end-caps for high durability and environmental resilience.
- Dust & Weather Protection: Equipped with an aluminium mesh front grille backed by an internal foam layer to protect internal driver cones from dust and environmental particulates.
- Acoustic Beaming Profile: Delivers a well-defined vertical sound beaming pattern designed for auditoriums and reverberant halls to mitigate unwanted room reflections and reduce acoustic feedback.
- External Tap Selection: Integrates a rotary tap/impedance selector switch directly on the bottom cover, allowing power adjustments without opening or disassembling the sealed enclosure.
